Best Abstract Price to researcher from the Interventional Centre
Anesthesiologist and PhD student Søren Pischke was awarded an Abstract Price at the 2009 Autumn Meeting of the Norwegian Anesthesiology Society. The abstract describes researh work performed at the Interventional Centre and is presented here: Hepatic and intestinal PCO2 measurement for real-time detection of hepatic artery and/or portal vein occlusion.
Liver ischemia is a potentially life-threatening condition occurring in the course of liver transplantation, liver surgery and circulatory shock. Following liver transplantation hepatic artery (HA) stenosis and portal vein (PV) obstruction occur in 3 – 12 % of the patients, and more frequently in children than adults. Today, standard of care is Doppler ultrasound and liver enzyme assessment daily. Accordingly, detection of severe hypoperfusion may be delayed. Continuous monitoring of intrahepatic and intestinal PCO2 may be an opportunity for early detection of ischemia as tissue CO2 increases during ischemia by HCO3 buffering anaerobically produced lactic acid.
Blood flow reduction in either HA, PV or both leads to alterations in intermediary metabolism in the liver. Intrahepatic and intestinal CO2 measurement as a marker for anaerobic metabolism detects these changes and enables correct diagnosis of the affected vessel.
New PhD Thesis from the Interventional Centre
Bjørn Erik Mørk defended his thesis Changing practices- A practice based study of cross-diciplinary technology development in hospitals from the Interventional Centre, Oslo University Hospital, Rikshospitalet, Faculty of Medicine at University of Oslo, Department of Leadership and Organizational Management, BI Norwegian School of Management, Oslo and Institute of Health Management and Health Economics at University of Oslo. This study examined why breakthroughs in knowledge may fail to be translated into medical practice. These novel practices often lack alignment with existing practices, or they cut across established professional boundaries and power structures. Despite this, we know that establishing practices across heterogeneous groups of actors, i.e. science, politics and industry, can facilitate interactive innovations. This project investigated how this was accomplished in practice in the context of cross-disciplinary technology development in hospitals. The dissertation is based on a longitudinal study of the Interventional Centre, Oslo University Hospital, Rikshospitalet, Norway.
MRgHIFU at the Interventional Centre
Magnetic Resonance guided High Intensity Focused Ultrasounds (MRgHIFU) has recently been installed at the Interventional Centre – Rikshospitalet by Philips Healthcare [1]. This is one of the few systems available in the world for completely non-invasive (without any inonizing radiation involved) treatment of Uterine Fibroids [Figure 1]. Patients treatment is about to be started in a few weeks.
MRgHIFU [2,3] may be a disruptive technology in the future by its total non-invasiveness compared to surgery or even radiation therapy where unwanted ionising radiation dose deposits always is an issue. Thus, target tissues (fibroids and tumours) can be destroyed without any device insertion in the body.

Interventional Centre partner in new European Commission FP7 Project: IIIOS
The Initial Training Networks project IIIOS is initiated by Andreas Melzer at University of Dundee. Reserarchers from the Interventional Centre have formerly collaborated with Dr Melzer through the Society for
Medical Innovation and Technology (SMIT). The Interventional
Centre will be responsible for research and training in MR image guided cardiovascular procedures. The Interventional Centre will participate both as a clinical and technological partner in this field. Research will include new concepts to improve the intraoperative MR suit and the hybrid angiographic room through the development of new intraoperative image navigation tools. Ole Jakob Elle and Per Kristian Hol will coordinate the
participation from IVC at a technological and clinical level respectively, and Frederic Courivaud will be responsible for the MR-related technology development.
IVS will be funded by 74 person months and given a total budget of approximately 4 mill NOK over four years by the project. The funding might be subject to changes through negotiations with the European Commision.
Interventional Centre partner in new European Commission FP7 Project: SCATh
The Smart Catheterization (SCATh) project is a spin-off from the Marie Curie project ARISER that The
Interventional Centre coordinated from 2004 to 2008. The SCATh-project was
initiated by one of the ARISER partners (Katholieke Universiteit Leuven) by Jos
Vander Sloten and Mauro Sette. The Interventional Centre is as a partner responsible
for the development of catheter tracking/navigation in MR and clinical
application and relevance. From The Interventional Centre Ole Jakob Elle
will coordinate the IVC participation, with Frederic Courivaud responsible for
the MR technology, Per Kristian for radiological aspects and Jacob

Live demo of new epicardial sensors
Reseachers from the Interventional Centre at Rikshospitalet Oslo University Hospital demonstrated 3 different new epicardial sensors live at a Workshop with the topic "Technology demo session: In-vivosensors in surgery" at the pHealth Conference on June 24th 2009. The sensors represents various stages of research based,experimental product development at the Interventional Centre. The sensors presented were a 3-axis accelerometer, an ultra sound sensor and a pCO2 sensor (Alertis Medical). All sensors represent a new type of sensors capable of local ischemia detection from heartbeat to heartbeat. The accelerometer and the ultra sound sensors are also able to detect changes in ventricular contraction patterns.
New PhD about Improved brain tumor diagnostics
Physicist and researcher Kyrre Eeg Emblem from the Interventional Centre
has in his doctoral work developed new methods for faster and more accurate
diagnosis of primary brain tumors. The dissertation took place on June 30th 2009
at Faculty Division Rikshospitalet, University of Oslo. Patients with suspected
brain tumors are currently referred to MR (Magnetic Resonance) imaging for
evaluation of tumor status and for planning of further treatment. With existing
methods, the results of this MR exam are dependent on the physician and thus
subjective, which in turn can have consequences for the patient's treatment
plan.
In the dissertation "Combined structural, microvascular and
functional mapping of brain tumors for improved diagnosis and treatment
planning” Kyrre Eeg Emblem and his colleagues have shown that automated
computer models can replace the current user-dependent image interpretation and
that such automated methods may provide more objective and reproducible results.
The dissertation present methods which are part of a larger database where
information and experiences from hundreds of previous MR exams are used to
improve prediction of disease status and expected response to treatment in new
patients. Especially analysis of blood volume measurements in tumors, so-called
MR perfusion imaging, has been a central element in the dissertation.
Master students needed for EHR access project
The majority of Norwegian hospitals have implemented electronic health records (EHR). The Interventional Centre (IVS) at Rikshospitalet has started a project to develop an automated translation service application to help patients understand the content of their EHR and thereby pave the way for better communication between health organizations and citizens. This is achieved by EHR text processing and cross mapping of medical terms to medical dictionary resources. The objective is to provide patients with electronic tools that automatically can display explanations of the medically complex EHR contents.
As part of the development of the automated translation service, our team at IVS is conducting studies to gather data concerning patient understanding of Electronic Health Record (EHR) medical documents. These studies look at the types of information provided to patients by healthcare professionals, how patients understand received information, as well as how they use information from their own EHR documentation. We are conducting our evaluation study with thoracic surgery patients at Rikshospitalet.
One of the world's first Single Port Laparoscopic Liver Surgery Cases
A surgical team lead by Bjørn Edwin MD, PhD, from the Interventional Centre and Bård Røsok MD, PhD from Department of Surgery Rikshospitalet performed a laparoscopic liver resection with the LESS device from Olympus this week, and became among the first in the world to use this approach on liver metastasis surgery. The tri-port system was used, and an image from the procedure can be seen to the right. The LESS device potentially leaves the patient with only one small and practically speaking invisible scar after surgery.
Another procedure that recently has been performed with Single Incision Laparoscopic Surgery (SILS from Covidien) technique is a cholcystectomy. This procedure was done by Elisabeth Hegstad MD, PhD, Bjørn Edwin and Arne Rosseland MD, PhD from the Interventional Centre earlier this spring. At the same time a similar procedure was performed for the first time in Denmark at Århus Hospital.
European endovascular aneurism repair (EVAR) Live Case Workshop
On May 11 and 12th 2009 European interventional radiologists and vascular surgeons took part in a EVAR live Case Workshop at Rikshospitalet. The workshop was hosted by Department of Thorasic Surgery, and was opened by head of department professor Odd Geiran. On the first day the vendor's technical aspects and clinical experiences were presented and discussed. Kirsten Krohg-Sørensen, MD PhD, presented the TAA experiences and material from Oslo.
